First time wiring for MODBUS. Can the power supply wires and the MODBUS communication wires be apart of the same multi-pair cable?
 
Sure, an unused twisted pair can be used to transfer the DC Voltage required by the Modbus modules.

I have used a simple multi-pair twisted shielded instrument cable for this.
